Vehicular Ad-Hoc Network

In today's scenario, there are various rising applications of intelligent transportation system that lead to the development of a new kind of ad hoc network. Nowadays, this network is hitting the streets as Vehicular Ad-hoc NETwork (VANET). VANET allows vehicles to communicate with each other and also with a roadside infrastructure that provides multiple applications from transit safety to driver assistance and browsing worldwide web (internet). It is a form of mobile ad-hoc network which usually utilize the roadside equipment. In this paper, the authors will further discuss this topic by studying and analyzing the localization process in VANET applications and finally focus on how these techniques can be combined to localize the vehicles.
